This paper evaluates the causal impacts of an early childhood home visiting program for which treatment is randomly assigned. We estimate multivariate latent skill profiles for individual children and compare treatments and controls. We identify average treatment effects of skills on performance...

This paper uses random assignment to estimate the causal impacts on child skills of a widely emulated early childhood home visiting program. We show the feasibility of replicating it at scale. We estimate vectors of latent skills for individual children and compare treatments and controls. The...
